Like most modelers with decades of experience, I've collected a good number of #1 knife handles, from the simple to the complex. Most are useful for some purposes. For example, I have one with a retractable blade (for traveling use) and an original Xacto I use with #18 chisel blades because I can hammer on the aluminum handle. But this is the handle I like best, and it's the one I use most. It fits well in my hand, doesn't cause cramps after long use (carpal tunnel is a bitch), and it doesn't roll. I don't even bother putting it back in the toolbox, but leave it out on the workbench (along with a package of #11 blades) for quick access. If I could only have one handle, this would be it.

Best hobby knife I have used. Fits hand very well, comfortable to use. Easy to change blades. Use on World War 1 model kits. great for cutting EZ line in tight places.

Loved the first one so much I bought a second one for my other modeling location. Grip is super comfortable and works great in several different hand positions. The only reason I haven't gotten rid of all my other handles is because I only keep a chisel tip in them.
